Description of Work: Taking advantage of an Angie's List special, Calvert was contacted to check our quite old gas furnace. The service person was prompt, professional, and thorough. Unlike several other companies, Calvert was in no way interested in bait and switch. Their honesty and forthrightness was both highly appreciated and unusual in the best way. Don't hesitate to call Calvert for your heating and cooling needs... they are good!

Used them for an estimate but went with another company based on price only. On the positive side, I found their office staff and the salesman to be responsive, professional, punctual and flexible. They scheduled at my convenience and the salesman arrived on time. He took his time looking over the existing (oil) setup and calculating what he thought I would need for the new (gas) setup. He was patient and willing to answer all of my questions fully, and was not pushy or aggressive in any way. The only negative was that their bid was the highest - and significantly so - of the four I obtained for this project. However, I would definitely ask them for a bid on any future work I consider.
Description of Work: Estimate for installation of gas piping, emptying and removal of oil tank, removal of oil furnace, and installation of new gas furnace in a house.

I don't remember the price but it was reasonable. My only issue was that when they were cutting into my drop ceiling in the basement, they made a few bad cuts and just put the material back in and it didn't look nice. All in all i was happy. I moved to a new house in 2005 but I have no service contract as of yet (brother in law was doing checkups) but am planning to call Calvert and have them give me a quote.

They scheduled the appt. for the very day I called, which was impressive. However, when Jon, the technician arrived, he said the unit was completely iced over and we would have to leave it turned off until the next day when he would return to evaluate the unit. He arrived the next day at exactly the scheduled time. However, he was unable to find anything wrong with the air conditioner, and proceeded to tell us that we needed a new furnace. I said that another company had recently been out to look at the rusted out area of the furnace and had told us it was just the casing that was rusted and nothing needed to be replaced. Jon asked who had come and when I told him he said you can't compare them to him - he is a professional with 12 years experience and that other company hires drug users off the streets. He said they weren't even a legitimate company - whatever that means - as we've been using them for oil delivery and cleanings for 18 years. Anyway, back to the air conditioner problem. Jon told us that the air conditioner was installed wrong, couldn't be fixed, and it couldn't possibly have ever worked. I argued that I've lived in this house for 18 years and never had a single issue with the air conditioning which I use A LOT until that day. He continued to argue that it couldn't possibly have ever worked. He said no one would be able to fix it and I would need a new one. I asked how much a new one would cost and he said he couldn't tell me, because I would hate him. I told him that I didn't like his attitude and the way he bad-mouthed the competition and his response was "Well you can't please everyone all the time. That will be $99". However, he is in a service field, so I disagree - if you don't please people, you won't continue to have a business. Fortunately since turning my A/C back on, I haven't had any problems - but then again, I have to remember that it isn't even working according to Jon!

They came on a Sunday when out 23 year old Centeral A/C died and replaced a couple cheap parts and did not recharge system as it would be too expensive if we chose to replace the system. The system died again which was expected with in 2 weeks so we were glad we did not pay to charge the system as reccomended not to charge it would have been a waste of money. Calvert was great they gave us a window unit for the couple of days it took before they could get to our house to replace the unit. The Techs that came to the house were very perfessional and polite overall a great experience. We had an issue with our Condo and the way the condensation drainage was routed out of the condo. Calvert was wonderful upon our inspection they fixed what our Condo Assocation required no questions asked and at no extra expense to us . Over all it was a good experience and will use them again for all our HVAC needs.C
Description of Work: They came to the house on a Sunday when the 23 year old Central A/C unit died. Calvert replaced parts and got it up and working so we were not dieing in the heat wave. This was a mininal expense. We did not charge the unit upon Calverts reccomendation as the unit needed to be replaced and it was on borrowed time. The A/C died again 2 weeks later we were hoping for longer but hence it was not to be .... Calvet took good care of us and I would reccomend them any day ...

I was happy from my call to the company, the same day service and the professionalism of the technician. My only concern was the additional $99 that was charged in addition to the labor and parts.
Description of Work: A/C did not work. Service technician replaced a damaged part . His explanation helped me to understand the problem.I would have liked the $99 service call be deducted from the charge.

They charge $99 to come out and look and that's not even applied to your balance if you decide to purchase something. I decided to have them come out anyway, based on good reviews here. The guy was very nice, and seemed very well informed as to how the system worked. He seemed very forthright. He hooked up a machine to my heater and said it was fine. He took measurements for the flue piece and said he was going to email or call with a price. However, he couldn't answer my question about moving vents (and I had told the scheduler what I wanted to ask), so he scheduled another guy to come out the next day to give me price for all the work together. The next guy was also nice. I think he said $1,150 or something, to move the two vents, and change the flue. I decided not to get work done by this company because I got a better price elsewhere. I never heard from the first guy about the price for just the flue, which is the one thing I was sure I wanted done. I probably would have bought that and a cleaning/tune up if I'd heard back from him.
Description of Work: I wanted to replace the metal part between my heater and chimney, and ask about moving some ductwork in the basement and relocating 2 vents. I also asked about heating and cooling for the attic, which is currently unfinished.

All work was done in one day (8 am to 4 pm). All my flooring and stairs to the basement were covered before they started any work. A second truck delivered the appliances, unpacked them in the driveway, removed all the packaging, cleaned up and left. No "downtime" or wasted time on the job. They replaced the foundation under the compressor unit in the yard, before they installed the new unit. The "intake and exhaust" pipes are flush to the outside wall and covered with a louvered plate that looks very nice. No "gooseneck" type pipes sticking out of the wall like some I've seen. A week after the work was done, they sent a company inspecter to check the work done.......and the county also sent an inspector to check also. Both commented on the "nice job" done!
Description of Work: Calvert replaced our original gas heater and air conditioner in 17 yr old home. We love our new 95% efficient Trane system. Reliable and professional sales staff and the technical crew who did the work were exceptional! I'd highly recommend them to anyone.

The process was quick fast and in a hurry, I was pressing for time, the job was started early that morning and it was done NLT 1:00pm.
Description of Work: My purchase from Calvert Heating Company was truely a good experience, the technicians were very knowledgeable and professional. I would recommend them for anyone that's in need or have a strict budget to work with. Also, one does not have to worry about them trying to drain your pockets dry, during these current times when money is very tight and scarce unlike most companies.

I got bids from 4 various HVAC contractors. What made the difference was that Calvert was thorough in evaluating the system I needed. They went through the house looking at my present system and pointing out what would be necessary with a new system to make it more comfortable and efficient. While the other contractors also went through the house it seemed they packaged a lesser AC with a very efficient furnace to lower their price. They also didn't pay attention to my electrical panel box or duct work. Calvert not only packaged a great HVAC system for me, their price was a little lower. It was a two day job and they came promptly, had their electrical sub contractor scheduled properly to coincide with their work. Everything went well without a hitch from beginning to end. The workers were courteous, professional and skilled. At the end of the job, they went through the operation of everything, gave me all the equipment manuals and cleaned up thoroughly.
Description of Work: The work included replacing a 32 year old oil furnace with a new gas high efficient burning furnace, replacing a 20 year old AC system with a new high efficiency AC system, replacement of a 50 gallon water heater, install a new 150 amp panel box, install another return air duct, outfit where needed any new ducts to connect new heating system and seal all existing ducts.

They are good. The service was gratis. I belong to their service plan and it is $12.95 a month. They come out and check the air-conditioner and they check the heater in the winter. I thought their employees were excellent. There was a young man that used to work for them at one time and he lived at the back of my house. That's how I found them. They are not cheap, but they are not the most expensive either. They are reasonable. I had been using another company and I found their prices to be just absolutely outrageous. That is why I switched to Calvert. Their quality is excellent. I have never had any problem with any of the people that have come here. I have never had a problem getting hold of anybody in the company. They are probably tied up with the plumbing company in some way or another.

After so many years of maintaining it, they told me I needed to replace my unit. I asked them for an estimate and they told me it would be $3000. I was not satisfied with that price, so I shopped around to see what others had to say. I got the job done from someone else who quoted me 1/2 of what Calvert did. More over when the guy came out to try and fix my unit originally, he had a manual in his hand which to me, seemed a bit incompetent in his work. He then had to call over his friend and even with him there, they could not figure out my furnace. The guy I had before them had no problem with it.

The AC on our 5 year old heat pump died suddenly on a Thursday. By the time I figured out it was the compressor and I wasn't going to fix it myself it was Friday night. I emailed Calvert that night along with a number of other HVAC contractors. I was contacted early Monday and was told that they wanted both my wife and me to be present for the estimate and quote. I was not pleased about that, since it was both inconvenient and typical of a pressure sale scenario. Communication was a bit confused, but finally got time set up for an estimate Thursday evening. I was running late and couldn't make the appointment, but my wife liked the estimator, who provided a professional and competitive proposal for the work. They ended up as my second choice of the five contractors that bid on the job.

They are phenomenal people. The integrity of the company stands out. Their price was slightly lower than one of the other quotes. I have never seen two more polite, hardworking, knowledgeable young men than the technicians who came to do the work. It took them over ten hours, and they worked straight through. They were wonderful in explaining everything that I needed to know about the system. They were terrific. I would recommend them to anyone. Within a week or two after the installation was done, they sent a different tech out to check their work. It took him close to two hours to go through and check everything. I thought that was something.

My air conditioner was dead. I called in the morning, and the sales person was there that afternoon. He was informative and did not try to sell me more than I needed. I had had two other quotes and his was the most reasonable. The installation was scheduled for 2 days after I signed the contract. The techs arrived promptly and worked professionally to complete the job. They answered any questions I had. I received a follow-up call from the company. Overall, it was a very pleasant and easy experience.

I had a new heating and AC system installed in August of 2010. The work was done quickly, cleanly and on budget. The installation techs were courteous and informative, and I was kept apprised of progress during the job. After the job was complete, they took the time to walk me through the system, including how to program my thermostat. Additionally, they were also extremely honest. During the loading of my furnace at the warehouse, it received a small dent, and the gentlemen installing the unit noticed it when they brought it down to begin the install. I would not have realized this if the install techs had not pointed it out. They offered me either a discount or a new unit. Since it was clear the dent was extremely minor and only cosmetic, I chose the discount. I would not hesitate to recommend Calvert for basic maintenance of your system, or use them for purchase and installation of a new one. They are competitively priced, and you cannot beat the customer service.

He said he had to go back to the office and email me the presentation. This was on Thursday. I get an email with the formal presentation from him on Monday or Tuesday. I replied right away and asked him who to call so I could make the down payment arrangements. He never responded. I sent him another email advising him that I was ready to go and when could we schedule this. He never responded. My life is busy enough and I don't have time to chase down someone that obviously doesn't want my money. I had money in hand and was ready to pay him a fifty percent down payment. I ended up going with Joseph Frederick and sons which will replace the unit for a thousand dollars less than Calvert.
Description of Work: No services were preformed. I called to schedule an appointment to replace my central air conditioner unit which had failed. They sent their sales guy Andy. He was on time and gave a complete thorough presentation of the work to be done. He explained why the existing lines in the house would be replaced and what new unit they would be bringing in. The price seemed fair so I suggested he schedule me a time. At this point I advised him that since I work in a cal center 10+ hours a day email was the best way to reach me.

Chris, the HVAC technician from Calvert, found the problem in about five minutes. The pipe that discharges water was backed up and needed a thorough cleaning. Also, there was a faulty switch. Chris took the time to explain the problem and how to fix it. He was polite and left his work area clean. I felt the price was fair and the work was definiterly comleted in a timely mannner. Good job.
